>whatever happens in America must happen in China too.
No, because PRC literally could not do what US did... they simply didn't have access to enough compute to dump so much $$$ capitalization for SOTA race. On the other hand, on paper US WITH MORE compute and (currently) CHEAPER compute can put forth cheaper models to undercut PRC open models... but functionally they can't for the same reason cheap PRC operators can't win in US - geopolitics. Undermining PRC AI requires giving PRC cheap US AI on cheap US compute which is sanctioned. But ultimately that is entirely irrelevant to the fact that CHEAPER US models will undercut EXPENSIVE SOTA US models. The undercutting is not symmetrical. US companies can use cheap PRC hammers (or even cheaper US hammers) to break $$$ US SOTA. US who on paper can provide even cheaper hammers to PRC... but cannot sell those hammers... so PRC stuck using cheap hammers... and since PRC never had chance to spend $$$ on SOTA, there's no equivalent valuable things to break even if they had cheaper hammers.
> trillions of dollars of investment going into these companies actually makes sense
We know the context for which those $$$ investment makes sense... if SOTA held meaningful lead to sell high volume of $$$ tokens which was hedge 1-2+ years ago when years of $$$ commitments were made. But doesn't seem to hold anymore, ergo it no longer makes sense. Microsoft had decades to build ecosystem and moat, just like adobe it was, actually hard and high friction to move away. People are switching models all the time. SOTA AI only labs has much less moat than Microsoft or other incumbent tech with decades of overlapping capture mechanisms.
> I think as a productive exercise someone should run this argument and explain why Chinese companies won't also be eaten alive
The productive answer is THEY ARE ALSO BEING eaten alive.
The even more productive answer is PRC commodity AI doesn't have to win for US SOTA AI to lose.
There's just not much meat on PRC AI bones so they are losing billions instead 100s of billions / trillions. Like there is ongoing domestic AI involution irrespective of US SOTA. Literally the primary reason PRC AI was forced to go free was because DeepSeek is billionaire side project who priced his hobby as free which set economics for all other players. Being sanctioned/compute constrained = they figured out how to close SOTA gap on the cheap but also set ceiling on how much they can lose on race to bottom. In so far their SOTA aspirations, again refer to DeepSeek, he takes some couch change from hedge fund gains or investors, and throws it at smart people and hope it's enough. If its not then they'll probably stop too. What PRC not going to do is mobilize resources equivalent to several % of GDP concentrated in few entities for SOTA AI, at least not until their compute is sorted, in which case competitive exposure / risks becomes symmetrical. In the mean time, things are not symmetrical and arguments against economics of US SOTA AI does not apply to PRC commodity AI.
